About "ipvs" and "keepalived"

[WangSteven]

Hi,
I used freebsd 9.1, just found "ipvs" and "keepalived" no longer exist in the ports.
Port:   net/ipvs
Moved:
Date:   2011-12-28
Reason: Has expired: Designed for FreeBSD 5.x, which is no longer supported
Port:   net/keepalived
Moved:
Date:   2011-12-28
Reason: Has expired: Depends on net/ipvs, which is scheduled for deletion

Is that means freebsd 9.x not support lvs and keepalived or just we can't install by ports? Is there any similar software like that supported by freebsd 9.x?

Please help,thank you.
